Los Ancares

Los Ancares is a district in northern Spain, which is noted for its unspoilt landscapes and ecological importance.

[1] The area takes its identity from the Sierra de los Ancares mountains which form a political and linguistic boundary between the autonomous communities of Galicia and Castile and León.

The Spanish term Los Ancares Leoneses is sometimes used to refer to the zone on the Castile and León side of the sierra, which is in the basin of the river Sil.

The area is a projected World Heritage Site, which would also include Somiedo Natural Park in Asturias.

[2] Fauna includes the Cantabrian brown bear.
